The Gladiator MKII is a great stick and it's backed up by a equally powerful software. Just open VKBDevCfg and program the buttons in any way. If you want your pinkie button to act as a regular button you could do so. If you want it to act like a button on a short press and as a shift key on a long press you could also do so.
You could also upgrade your joystick to a Kosmosima grip (https://vkbcontrollers.com/?product=scg-space-combat-grip-kosmosima-stand-alone) by installing an adapter kit (https://vkbcontrollers.com/?product=gladiator-upgrade-kit-lite-w-mcg-bundle-2) following this guideSource: https://www.youtube.com/watch?v=x_LXh5LTJL4
. The adapter comes with stronger springs too.
If I wasn't using the Gladiator as an interim stick, and the shipping cost wasn't so prohibitive, I might consider it.
